ROK Jr.'s Beginning Builder features larger, press-fit blocks and roadway pieces for easy assembly by four and five year olds. Beginning Builder is action-packed fun with driving, loading and unloading capabilities - and an all new, fully featured front-loading Dump Truck! To drive it, we created a new wireless infrared controller dedicated only to the ROK Jr. Dump Truck. It offers intuitive, easy-to-master steering and dumping controls - and it fits comfortably in one hand.

Now they've taken that same technology across all the vehicles. It's called ROK STAR.

The red balls are slightly smaller than the blue balls. As the balls roll down the main ramp, the blue balls roll right over the smaller holes, continuing to their ramp. The smaller red balls, however, fall right into the smaller holes, heading down their own ramp.
